IMPROVEMENT IN TEMPLES FOR LOOMS.

. Specication forming part of Letters Patent Nol59,050, dated January26, 1875; application filed December 9, 1874.

To all whom it may concern:

Be it known that I, EDWARD S. STIMPsoN, of Hopedale, of the county ofWorcester and State of Massachusetts, have invented a new and usefulImprovement in Temples for Looms 5 and do hereby declare the same to befully described in the following specification, and represented in theaccompanying drawings, of which- A A l A Figure 1 is a top view of aroller-temple, containing my invention. Fig-2 is a longitudinal sectionof it. Fig. 3 is a transverse section of it, taken through thesupport-plate stand or carrier. Fig. 4. is a transverse section of thetemple, taken through one of the friction-rollers to be described. Fig.5 is a top view of the temple, with the cap of its case removed. Fig. 6is an outer side elevation of the temple. Fig. 7 is an under-side view,Fig. 8 an edge elevation, and Fig. 9 a transverse section, of the cap ofthe shank-case.

My invention is, properly speaking, an improyement in the well-knownDutcher Temple.

In carrying out my said invention, I construct the case Afor receivingthe toothed roller, case supporter or slide-bar or shank B, with twochambers or recesses, a a, for reception of two short frictionrollers orcylinders, b b. These chambers I arrange at or near the ends of thecase, one chamber being on one side and the other on the other side ofsuch case, as shown. Each chamber is to contain one or morefriction-rollers, b, against the peripheries of which the shank B is tobear. These rollers, while the shank is being moved forward or backward,

support it, and roll back with it and against the backs of the recessesor chambers. They are to prevent friction and wear of the shank aud itsbearings in the case, such as usually result when the case is withoutany such recess and rollers. The length of each roller corresponds withthe depth of its recess, the cap or cover C, and the bottom of therecess, serving to keep the roller in its upright position. The cap, asusual, I provide with an abutment, c, for the shoulder d of the shank tobring up against, in order to arrest the forward motion of the shank.From this abutment and the cap there is extended, in manner as shown, aprojection, e, to enter and fit in the upper part of the foremostfrictionroller chamber. The said projection e supports and guides thefriction roller, and by bearing against the front end of the recess athereof, relieves the front connection-pin g of the cover and case fromthe strain incident to the blows of the shank-shoulder against theabutment, such strain operating to cut off or loosen the pm.

The stop or shoulder to operate with Ithe front part It of the case inholding back the shank, and by the lateral strain of the cloth, is shownat i. In order that the front frictionroller may not prevent the shankfrom moving laterally for the shoulder z'to engage with the part h, Iform in the side of the shank, and at a short distance in rear of theshoulder i, a curved recess, l, which, when the roller is against therear end of its chamber, comes opposite to said roller, and therebyenables the shank to move laterally.

Furthermore, I provide the shank B with a groove or chamber, m, (seeFig. l0, which is an underside view of the said shank 13,) to receivethe helical spring D, for advancing the shank. At its ends the saidspring is provided with eyes 0 p, the forward one of which, when thespring is in place, is hitched upon lor receives a stud, q, projectingup from the bottom of the case. A pin, 1', going through the shank B andthe rear eye of the spring, serves to connect the spring to the shank.

From the above it will be seen that the spring does not encompass theshank ora rod arranged therein, and acts by contractile force to advancethe shank. With my application of the spring there is no danger of itbeing suddenly contracted and closed so as to break or be injured, as itis liable to when it encompasses the shank and acts by expansion todrive the shank forward.

The shank is to be provided with the roller case or trough s with itscover t, and adjustable shoulder u, all as usual, or as shown.

The case A has two flanges, o c, projecting from the opposite sides attheir lower parts,

as shown, each of said langes being beveled or inclined on its upperedge, as represented.

The temple carrier or plate E, which supports the case A, is providedwith a lip, w, to

overlap one of said flanges. Such carrier ex tends, as usual, underneathand across the case, and projects at one end beyond it a short distance,the part so projecting being provided with two inclined abutments, y y,whose edges next the case make obtuse angles with the top surface ofthecarrier. Between these inclined edges and the inclined ed ge of the neXtadjacent an ge QJ- of the case, screws zz, with tapering heads, asshown, are arranged. These screws screw looselyr into the carrier, inorder that they, on being screwed down against the abutments, may beforced by them hard against the inclined lian ge in manner to press thecase close up to the lip w. By applying the screws directly against theinclined abutments and ange, I avoid the use of a gib arranged with thescrew and iianges, in manner as shown in the United States Patent No.154,837, dated September 8, 187 4, and simplifying the temple.

I do not claim the combination of frictionrollers, moving on fixed axesor journals, with the case and shank of a loom-temple, such being shownin the United States Patent No. 9,502, granted to E. and W. W. Dutcher,December 2S, 1852, in which case the rollers were not in closedchambers, but were exposed, so that waste and dust could readilyaccumulate within, so as to obstruct their operations, all of which isobviated by my improvement, viz., hy having the rollers in closedchambers in the case; and besides by having the rollers to roll againstthe backs of the chambers there will be less friction and wear of-thenl.Nor do I clai m a gib arranged with one or more screws and flan ges, inmanner as shown in the aforementioned patent No. 154,837.

The improved temple described effects a great saving of power incomparison with most if not all other reciprocating temples now orheretofore used, for the large lateral strain of the cloth on theselatter temples necessarily induces much friction between the sides ofthe shank and their supports, such requiring a very strong and stiffspring to overcome this friction and advance the shank during therecession of the lay. rIhe lay in beating up had to overcome thisfriction and the elastic force of the spring. With my improvement a verymuch lighter spring or one with less power can be used, thus effecting asaving of power, and greatly reducing the friction and wear of therubbing surfaces.

I claim as my invention- 1. The shank-supporting case A, provided withthe closed friction-roller chambers a a, and their rollers b b, incombination, and arranged with the shank or bar B, all substantially asspecied.

2. The cap C, provided with the abutment c and projection c, arranged asdecribed, in combination with the case A, provided at its front end withthe friction-roller b, and its receiving-chamber a, all beingsubstantially as described.

3. The shank B, provided with the recess l and shoulder t', incombination with the case A, friction-roller b, and chamber a, allarranged as set forth.

4. rIhe shank B, provi'led with the chamber m, in combination with thespring D and case A, all arranged and operating together as set forth.
